I'm replacing the access door to my garage (not the garage door) with a pre-framed metal door from Home Depot. The new door comes complete with a threshold. My existing garage door frame has no threshold and there is no sill plate under the door; the door sweeps just above the concrete pad.

Temperatures here range from a low of -40 degrees to a high of about 95 degrees Fahrenheit. There's not a lot of snow, but the drifts sometimes gather in front of the garage (2 feet max). The slope is OK for rain.

I can either remove the pre-built threshold from my new door and install like the existing door, or add a sill plate for the threshold to rest on.

If I remove the threshold, will I weaken the structure?

If I add a sill plate, how do I fasten it to the cement pad and how do I keep moisture (particularly ice) from infiltrating?

Thanks.

If I understand what you got there You don't need a cill plate under the new door if its going directly on your garage floor.. What you do is silicone under it to stop water, bugs air from coming in.

Hey Daryll...600 posts too. Congratulations to you for stickin around and helpin

Silicone the door and enjoy. Just remember you may also need some support on the front edge of the sill/threshold. Sometimes adding a board underneath at the front helps. Just drill the board on to the face of the concrete and tapcon (blue concrete screws)with concrete screws if it needs it.

Enjoy.

Thanks, folks. The door's in, level, square, swings evenly and meets the jamb nicely all the way around. Couldn't have done it without your help.
